The liquidators are seeking payment of that amount from those directors.
Mainzeal's collapse into receivership on Waitangi Day 2013 sent shockwaves through the building industry. Liquidators said last year that the creditors were owed $151 million.
On the claims alleging reckless trading, Shipley, Gomm, Tilby and Collins deny them and say they "carefully and frequently" monitored the financial position of Mainzeal Property and Construction and sought external advice from Ernst & Young.
Shipley, Gomm, Tilby and Collins also say they were entitled to and reasonably did take comfort from forward work orders relating to the Christchurch rebuild.
Shipley, Yan, Gomm, Tilby and Collins are also accused of breaching their director's duties by entering into a debt restructure in December 2012.
Shipley, Gomm, Tilby and Collins deny breaching director duties and say Mainzeal Property and Construction had a limited role in the transaction.
Yan, who has separate legal representation, has denied the allegations against him. Kwan has not yet filed a statement of defence.
